Trinket Choice

[Skullknight157]

I'm new to playing a Mage so I'm not sure what to do in this situation. The three trinkets I currently have are a 900 Terror From Below, 885 Tarnished Sentinel Medallion, and a 905 Whispers in the Dark. My main spec is Fire. What would be the best combo? I know the Medallion trinket is really good even though it's much lower than the other two, which is why I'm not sure what combination to have. Thanks!

use the 885 tsm and the other 2 are very close with slight edge going to 900 terror
